Many people regret that they did not learn about Bitcoin earlier, and regret that they did not participate in Bitcoin investment from the beginning. But I think it is never too late to invest in Bitcoin. Some people may have learned about Bitcoin very early, and they may be afraid of this unknown new thing and its negative impact and will not invest.
As long as you believe in Bitcoin and hold it for a long time, you can get high profits when the price rises. Moreover, Bitcoin is still in an upward trend and there is still a lot of room for growth, and there is more time to invest in it to make a profit.
